We've done a heck of a lot of work on the design (with help from some forum members) but at this point it's unclear if we will proceed or not due the to complexity of the design, well at least the number of things that have to be done and it's a lot of work for two men and a dog. And one of the men (not me unfortunately) is currently motorbiking around Europe so I think we'll decide what to do when he gets back.
